Procedure

3-(2-Amino-4-chloro-6-fluoro-3-hydroxyphenyl)-1-methyl-6-trifluoromethyl-2,4(1H, 3H)-pyrimidinedione (0.50 g, 1.4 mmol) and 2-naphthoyl chloride (0.27 g, 1.4 mmol) were dissolved in 1,4-dioxane (10 ml) and the solution heated under reflux for 4 hr. Solvent was evaporated under reduced pressure and the product purified by column chromatography on silica gel (eluent, hexane-ethyl acetate, 8:2) to furnish the title compound (0.60 g).
